A Toy Model of the Information Paradox in Empty Space. (arXiv:1809.10154v1 [hep-th])  gr-qc updates on arXiv.org on 2018-9-28 12:43pm GMT Authors: Suvrat Raju A sharp version of the information paradox involves a seeming violation of the monogamy of entanglement during black hole evaporation. We construct an analogous paradox in empty anti-de Sitter space. In a local quantum field theory, Bell correlations… Read more →

Bouncing oil droplets, de Broglie’s quantum thermostat and convergence to equilibrium. (arXiv:1807.00569v4 [quant-ph] UPDATED)  quant-ph updates on arXiv.org on 2018-9-22 7:24am GMT Authors: Mohamed Hatifi, Ralph Willox, Samuel Colin, Thomas Durt Recently, the properties of bouncing oil droplets, also known as “walkers”, have attracted much attention because they are thought to offer a gateway to a better understanding of quantum behaviour. They constitute indeed… Read more →

International Workshop on “The Meaning of the Wave Function”

We are delighted to announce that the International Workshop on “The Meaning of the Wave Function” will be held at Shanxi University, Taiyuan (also known as the Dragon City), China, from October 12, 2018 to October 14, 2018. The workshop is organized by the Research Center for Philosophy of Science and Technology of Shanxi University.

Dimensional reduction via a novel Higgs mechanism. (arXiv:1806.07520v1 [gr-qc] CROSS LISTED)  hep-th updates on arXiv.org on 2018-6-23 1:03am GMT Authors: Saurya Das, Mir Faizal Many theories of quantum gravity live in higher dimensions, and their reduction to four dimensions via mechanisms such as Kaluza-Klein compactification or brane world models have associated problems. We propose a novel mechanism of dimensional reduction via spontaneous… Read more →

Quantum gravity tomography. (arXiv:1806.05643v1 [hep-th])  hep-th updates on arXiv.org on 2018-6-16 1:14am GMT Authors: William Donnelly The holographic principle posits that all quantum information in a region of spacetime is encoded on its boundary. While there is strong evidence for this principle in certain models of quantum gravity in asymptotically anti-de Sitter spacetime, it is yet to be established whether holography… Read more →

Why initial system-environment correlations do not imply the failure of complete positivity: a causal perspective. (arXiv:1806.02381v1 [quant-ph])  quant-ph updates on arXiv.org on 2018-6-09 12:56am GMT Authors: David Schmid, Katja Reid, Robert W. Spekkens The common wisdom in the field of quantum information theory is that when a system is initially correlated with its environment, the map describing its evolution may fail to be… Read more →
